A Correct answer
Explanation

 The mitral valve or bicuspid valve located between the left atrium and left ventricle, regulates the flow of blood.

Multiple choice

P. Jervell and Lange-Nielsen syndrome Q. Andersen-Tawil syndrome R. Angelman syndrome

  1. Only P

  2. Only Q

  3. Only R

  4. Only P and Q

  5. Only Q and R
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

This option is correct. Jervell and Lange-Nielsen syndrome and Andersen-Tawil syndrome are types of long QT syndromes that cause the cardiac muscle to take longer than usual to recharge between beats.

Multiple choice

Items related to heart belong to the ________ domain.

  1. cognitive

  2. affective

  3. psychomotor

  4. all of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In Bloom's taxonomy, the psychomotor domain relates to physical movement, coordination, and the use of motor-skill areas, often associated with the heart (physical activity/action).

Multiple choice

Monitoring and regulation of heart rate is an important requirement for diagnosis and treatment of cardiac patients. Which of the following instruments only stores those periods of heart rhythm that it recognises as irregular?

  1. Holter monitor

  2. Pacemaker

  3. Loop recorder

  4. Cardiac catheter
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Loop recorder only stores those periods of heart rhythm that it recognises as irregular. An implantable loop recorder is usually given to patients who experience heart-related symptoms such as fainting, light headedness, dizziness, seizure and frequent palpitations.

Multiple choice

Systolic heart failure occurs when the muscle of the left ventricle loses some of its ability to contract or shorten. Which of the following acts as the best determinant of the severity of systolic heart failure?

  1. End-diastolic volume

  2. End-systolic volume (ESV)

  3. Stroke volume

  4. Ejection fraction
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Ejection fraction is an important determinant of the severity of systolic heart failure. Ejection fraction is low in patients with systolic congestive heart failure.
